Boron Trichloride (BCI3)

Boron trichloride (BCl3) is a toxic, colorless, corrosive gas delivered as a liquid under its own vapor pressure. Portland customers who want a well-established, local producer of boron trichloride should reach out to Cryo-Source at 503-235-0168.

Boron trichloride has an assortment of classic utilizations, including as a starting material for the production of elemental boron. It has been historically associated with the preparation and refining of aluminium, magnesium, zinc, and copper alloys to eliminate nitrides, carbides, and oxides from molten metal, although the majority of these processes have moved away from North America.

It still has some use when mixed with other compounds as a soldering flux for alloys of aluminium, iron, zinc, tungsten, and monel. Most BCl3 in North America was previously used in the manufacture of electrical resistors, to help create a carbon film over a ceramic base. At this time, most Ultra High Purity Boron Trichloride (BCl3) is used in plasma etching in semiconductor manufacturing. This gas etches metal oxides by formation of boron chlorates.

Cylinder quantities of PurityPlus® High Purity Boron Trichloride are also distributed to many chemical research facilities and universities for use as a reagent in the creation of organic chemicals.
